Chapter 1 Configuring IPv6 MLD Snooping
Configuring IPv6 MLD Snooping
Configuring a Static Multicast Group
Hosts or Layer 2 ports normally join multicast groups dynamically, but you can also statically configure
an IPv6 multicast address and member ports for a VLAN.
Beginning in privileged EXEC mode, follow these steps to add a Layer 2 port as a member of a multicast
group:
To remove a Layer 2 port from the multicast group, use the no ipv6 mld snooping vlan vlan-id static
mac-address interface interface-id global configuration command. If all member ports are removed
from a group, the group is deleted.
This example shows how to statically configure an IPv6 multicast group:
Switch# configure terminal
Switch(config)#
ipv6 mld snooping vlan 2 static FF12::3 interface gigabitethernet0/1
Switch(config)# end
Configuring a Multicast Router Port
Although MLD snooping learns about router ports through MLD queries and PIMv6 queries, you can
also use the command-line interface (CLI) to add a multicast router port to a VLAN. To add a multicast
router port (add a static connection to a multicast router), use the
ipv6 mld snooping vlan mrouter
global configuration command on the switch.
Note
Static connections to multicast routers are supported only on switch ports.
Command Purpose
Step 1 configure terminal Enter global configuration mode
Step 2 ipv6 mld snooping vlan vlan-id static
ipv6_multicast_address interface interface-id
Statically configure a multicast group with a Layer 2 port as a
member of a multicast group:
• vlan-id is the multicast group VLAN ID. The VLAN ID
range is 1 to 1001 and 1006 to 4094.
•
ipv6_multicast_address is the 128-bit group IPv6 address.
The address must be in the form specified in RFC 2373.
• interface-id is the member port. It can be a physical
interface or a port channel (1 to 48).
Step 3 end Return to privileged EXEC mode.
Step 4 show ipv6 mld snooping address user
or
show ipv6 mld snooping address vlan vlan-id
user
Verify the static member port and the IPv6 address.
Step 5 copy running-config startup-config (Optional) Save your entries in the configuration file.
